Popping right knee

[Abarnes]

Good that you caught the seatpost had slipped - run a band of electrical tape around it at the top of the seattube so you notice it right away.

You may still have some inflammation in the area, with an increase of sinovial fluid as a response to the injury. The popping sound when you bend the knee is displacement of the fluid and gases in and around the joint.

If you're not experiencing pain all good - but no reason not to do gentle massage of the tissue in the area to help flush toxins.

Also, you mention riding in hills and with a trailer - consider riding one gear lower as well as remembering to downshift before coming to a stop. Starting up again in a lower gear reduces the sheer force on the knees.

I agree with the gearing advice, do the knee a favor and use the gears if you can.

My right knee has an interesting series of pops it used to go through when I'd ride, pop pop pop POP and then it would be done for a while - like popping a knuckle. It was annoying because I'd have to get it to POP or it was distracting. It sounds very similar and I would agree it has to do with seat height, at the right height my knee does NOT pop. It's a very subtle difference, as well, maybe two millimeters!

Gbunker - sounds like what my IT band does.

+1 to this.

Symptoms of my left knee right before it began to hurt a lot and I entered into PT for 2 months.

There are tons of good IT band stretches, I highly recommend them
